Oxygen Absorbing Bottle Caps - 120 Count
Perfect caps, 99% of the time they work
For many years, I have ordered "Oxygen Absorbing Caps" from Midwest Supplies. Until recently, the orders were always fulfilled with "LD Carlson Co. Silver Oxygen Barrier Crown Caps" in a 144 count bag.
I always use the Silver Oxygen Barrier Crown Caps because they give me a near 100% success, event with re-cycled thin-lipped beer bottles. In contrast, I found the alternative "Fermenters Favorites" colored caps to be very unreliable with anything but the best-quality thick-lipped bottles. On close inspection, I think the difference is due to sightly thicker metal and a better seal on the LD Carlson product which improve the odds of getting a straight fit and tight seal on inferior bottle tops.
Instead of my usual delivery of LD Calson caps, I see that Midwest Supply has switched to "Fermenter's Favorites Oxygen Absorbing Caps" in a 120-count bag. As I have still have a stock of LD Carlson caps, I'll run a 50:50 experiment on my next few bottling batches to determine whether there is a difference in performance. If I observe no difference, then all will be well!
Worked great with my floor capper!!!
